- Application 'fi led October 5,. 1 92s. swarm. teasers My invention: relates: to globe holdin dey vices, more particularly to devices of the spring suspension type for holding globes i which are usediin connection with lighting.

fixtures; v I

Heretofore, 1n gas and electric lighting fixtures a three-point screw suspension device has been commonly used for holding the @gl'ob'e- Suchv devicesaccomplished their pur- I pose satisfactorily for small globes but for globes of: large .dia1neter.theweight of the globe is such that multr-p01nt screw suspension isjunsatisfactorybecause of the danger of the lobe breakingdueto too greata strain b 0 I at the pOlIItSQI suspension.

, It is among the objects of nyinventionto overcome the disadvantages of previous structures and to provide a globe holding means which shall be simple, compact and positive in operation.

It is a further object ofmy invention to rovide a spring suspension globe holder iaving latches co-operating with an equalizing spring and the globe.

In practising my invention, I provide the usual socket base and employ therewith a globe seat upon which a spring member rests. I further provide latches which co-operate with the spring member and with a globe supporting ring to make dust proof contact between the globe opening and the globe seat.

In the accompanying drawings, constituting a part hereof and in which like reference characters indicate like parts,

Fig. 1 is a View, partially in section and partially in elevation illustrating one embodiment of my invention,

Fig. 2 is a sectional view taken along the line II--II of Fig. 1;

Fig. 8 is a plan view of one of the latches;

Fig. 41 is a side view thereof, and

Fig. 5is a plan view of the globe holding rlng.

The base member 1 has formed integrally therein the usual socket 3 and lamp 4. Upon the globe seat or base 2 rests a spring ring 5. (Jo-operating with said spring member are the latches 6 and 7 which pass through openings 8 and 9, respectively, of the globe seat 2 andalso through the washers 10 and 11, respectively, which cover said openings.

The globe 13 may be of the usual types employed. The opening of theglobe has a fiat ground (portion Which adapts it to be seated against the. globe. seat 2and= thus: make a dust proof contact. therewith, the globe ring 15, having an offset portionlfi and "lugs- 17 opposite thereto for clamping bolt 18 alongrthe upper: portion 190f the globe. There is thus, provided a continuous engagement between the globe and entire circumference.

The latches-6 and 7 comprise body. portions 20 having ears 21 and 22 formed in the-upper 5 and lower parts thereof, respectively. 'Ihe ends 23. provide means. for actuating the same. 7 p To assemble the structurgthe ground surface 14; of: the globe 13 is. brought1i=ntocontact with tlreeseat2u Thesl atches 6-. and 7 the ring for its a are. inserted in position and. ears ill-arev caused:

to engagethe spring ring 5 The ear 22. of. latch 6 may then be inserted under offset portion 16 of ring 15 which holds globe 13. The ear 22 of latch 7 is sprung under bolt 18. The tension of spring ring 5 holds the globe in dust-proof contact with the seat.

To remove the globe, it is merely necessary to press down on handle 23 of one of the latches while supporting the globe with the hand. The globe is then released allowing it to swing about the other latch as a hinge.

In this position, the globe may be cleaned or the lamp renewed and the globe then replaced. Or, the other latch may be released in a similar manner and the globe removed from the fixture. My invention provides a globe holde which allows no dust to. pass into the globe and settle therein, thus preventing the 'dimming or subduing of the light. The globe is easily detachable and, when desired, one of the latches maybe used as a hinge member for the globe to facilitate cleaning or re-- placing of the-lamp. The spring suspension provides for an equalizing of pressure at all "t f ttbt th lbcd lb therewith the globe seat 2, and has placed s 0 con ac e Ween 0 e m 0 8 seat. The spring suspension also compensates for irregularities in the ground contacting portion of the globe and seat. The globe ring makes substantially even contact s with the globe whether the globe is perfect in weight without any danger of breakage because of strains. Because of the simplicity of the structure,the manufacturing costs are low. c

It is obvious that my invention is suscep- V tiblefof numerous'cha'nges and modifications Q and that I have shown and described but'a single form thereof. A V eqfiallywell adapted for holding globes in ot For instance, itis er than the inverted position. The latches may be made an integral part of the spring or maybe secured thereto. I desire, therefore, thatno limitations shall be imposed on my invention except such as are indicated'in the appended claims.

I claim as my invention: 1'. A globe; holder comprising a canopy, a

A base attached to said canopy, a plurality of suspension members, a globe ring, a resilient equalizing spr ng cooperatlngwith said base connecting and supporting said suspension members, said suspension members cooperating with said ring, base and spring whereby dust-proof engagement is made between the globe and base.

2. A globe holder comprising a canopy, a base attached'to said canopy, a plurality of suspension members,.a globe ring, a resilient equalizing spring cooperating with said base connecting and supporting said. suspension being pivotally secured to said sprin a ring for securing a globe to said latches 1 6.
